Introduction: The maintenance and improvement of cardiorespiratory capacity is closely related to the promotion of health. Physical training programs aiming to improve physiological systems, such as respiratory and cardiovascular systems, are recommended, especially aerobic physical training with moderate intensity (~ 60% VO2peak), which is performed in a long duration (~ 30-60 minutes). The adoption of intermittent high intensity training programs with the goal of reducing body fat and improving aerobic fitness is increasing. However, the effectiveness of this type of physical training program is still incipient. Objective: The aim of the present study was to evaluate the effectiveness of different aerobic training programs on aerobic fitness in young adults. Methods: Voluntarily participated in the study 30 healthy young adults, male, physically active, normal weight, which performed three weekly sessions running exercise on treadmill. The subjects were randomized to one of the following experimental groups: Intermittent high-intensity training group (TAI, 1: 1 - 1 minute of racing at 100% vVO2peak and 1 minute of passive recovery, totaling 5km each training session, N= 10), Continuous training group of moderate intensity (TAC, 70% vVO2peak, totaling 5km each training session, N= 10), or control group (did not perform any type of training, N= 10). Oxygen consumption was measured by the Quark PFT Ergo gas analyzer (COSMED®-Rome). The maximum speed reached in the incremental test was defined as vVO2peak. Statistica 12.0 was used for statistical analysis and it was adopted p <0.05. Results: After 6 weeks of application of the different physical training protocols, none of the experimental groups showed a significant increase in VO2peak values (moment and group, p> 0.05). In addition, all trained groups exhibited maximal velocity increase after 6 weeks of training when compared to the control group (p <0.05). Conclusion: Taken sets, our results demonstrate that the adoption of different exercise training programs (intermittent high intensity or continuous moderate) to the short-term (6 weeks) can cause physiological adaptations related to improvement in aerobic power, but not aerobic capacity in young adults.
